This patch adds missing inline wrappers for nla_get_le32 and nla_get_le64. The 802.15.4 MAC byteorder is little endian and we keep the byteorder for fields like address configuration in the same byteorder as it comes from the MAC layer. To provide these fields for nl802154 userspace applications, we need these inline wrappers for netlink. Cc: David S.
